Vixen Porta II Alt-Az Mount

Vixen Porta II Mount

The lightweight altitude-azimuth (Alt-Az) Porta mount can be the heart of an exceptionally portable telescope/mount system. The Vixen Portamount II features a newly designed friction system for quickly pointing toward the target and tracking it with the 360-degree slow-motion controls. No fumbling with clutches or sectional slow-motion controls! Leave the heavy counterweights with the equatorial mounts: simply balance scopes up to 155 mm diameter on the altitude axis and start viewing!

The Vixen Porta Mount II comes equipped with two fine adjustment handles for whole circle slow motion in both directions - a necessity when searching for and tracking celestial objects. Or how about adjusting the friction level so the mount simply stays where you put it? In addition, the Vixen Porta is a great mount for terrestrial viewing, too. Its gear drives make it a simple matter to precisely track a planet or a ship on the horizon by just turning the elevation and/or azimuth control handles.

The Porta in this Vixen mount's name stands for "portability"... and with good reason. It weighs only 12 pounds including tripod - yet will support a payload of 20 pounds.

The World-Standard dovetail attachment system on Porta II was developed by Vixen. This allows the Vixen Porta II Mount to accept various dovetail mounted optical tubes and binoculars - making it a splendid travel companion for hikers, birdwatchers, traveling astronomers and more!

The standard Vixen dovetail mounting slot with lock and safety screw is fully Vixen Sphinx and Great Polaris compatible. This mounting slot removes to reveal number-20 and M8-1.25-inch threaded holes for custom mounting solutions for your scope, too!. The PortaMount II features switchable slow-motion knobs, tension adjustment and disassembly tools, built-in tool storage bay, tripod tray and aluminum legs.

Words on the Vixen Porta II Mount

"For so many years the beginning astronomer was forced to buy a mount that was unstable and almost useless when viewing at high power. More often than not, the frustration of using an unstable mount resulted in the telescope only being used for one night and being left in a closet to collect dust. The Porta II mount changes all that. It is one of Vixen's proudest designs. The combination of smooth movement, rigid design and stable platform makes your first use a pleasure and will bring you back to view more and more of the night sky." -- Mr. StarGuy

Questions & Answers

Ask a Question
  • I have an explore scientific refractor, 127ED. It weighs 22.5lbs with the mounting rings. Would this be pushing the weight limit too much? I have it mounted on an Orion skyview pro goto mount that has also has a 20Lb payload but it handles it ok.

    It's not just the weight, but also the torque due to the length of the Explore 127ED that would make the Porta Mount II not an ideal choice for that scope. The Skyview Pro Goto mount is underrated at 20 lbs (that's a good imaging weight limit, b

  • Will the Vixen Porta Mount (version I or II) handle the Vixen VMC200, 8-inch catadioptric? Outer diameter of OTA is about 10 inches. Weight of OTA alone is 13 lbs, but 15-16 lbs with heavy accesories (2" diagonal, eyepice, finder).

    In the past, Vixen used to sell a package with the VMC200 on the Porta Mount II, so they consider this a usable setup. I would argue that this is the heaviest setup that is recommended for the Porta Mount II, meaning that it is too heavy for the original
